The INSIDER Summary:

To fulfill a childhood dream, Micky Thorton started building a pool in his backyard on Labor Day in 1993.

The gigantic swimming hole now has waterfalls, sprayers, a rope swing, a diving board, and more.

The Thortons now welcome visitors to their pool for a fixed donation fee.

So far, they have hosted kids' soccer teams, birthday parties, weddings, and even the Japanese national baseball team.

Growing up, Micky Thornton dreamed of building a pool in his backyard.

When he was 39 years old, Thornton set out to fulfill his childhood wish — in one gigantic way. After moving to Covington, Tennessee, with his family, he began building his backyard pool on Labor Day in 1993.

Initially, the swimming hole was just 20 feet deep, lined with a polyethylene mat. But Thorton wanted the pool to be so large that "you could swim around it and not feel like you [were] trapped in a little box," WREG Memphis reported.

Today, the massive pool is made up of 320 yards of gunite, 40,000 pounds of steel rebar, and more than half a million gallons of water, by Thornton's estimate.

With rock-lined waterfalls, sprayers, a rope swing, a diving board, and more, the pool now looks straight out of a water park.

Luckily, you can visit the Thorton's family pool for a fixed donation fee. All you have to do is book a reservation through their Facebook page.
